Hi Everyone -
Been a while for me here.
I just finished restoring a Chroma Polaris and have noticed a digital / computer noise in the background of my output.
It isn't effected by any of the controls other than master volume.
It is my understanding, from other conversations in this group that there were different grounding solutions for different revisions of the Chroma Polaris.
Has anybody had this issue, and if so, what was your solution?
Any help is appreciated.
